The federal tax shakeup will impact American lives in big and small ways for years to come.

Miserable married people should get a divorce lawyer on speed-dial. Starting with marriages dissolved in 2019, those who pay alimony can not deduct it from their taxes.

You may be figuring your own taxes, now that tax-preparation fees are not deductible. That goes for tax-prep software, too.

College sports fans are booing because next year they’ll be barred from deducting ticket fees as charitable contributions — and big-time university athletic programs are fretting about the possible hit to their bottom line.

Moving expenses are not deductible starting in 2018, except for active-duty service people. If your company reimburses your moving expenses, they’re not deductible.

Bicycle commuters are losing a $20-a-month reimbursement that some employers offered as a tax-free fringe benefit.

In a nod to the #MeToo movement, companies can’t deduct sexual-harassment payouts or lawyer fees if the settlement includes a nondisclosure agreement.

On the plus side:

The medical expense deduction has been expanded. Filers whose medical costs total 7.5 percent or more of adjusted income can deduct them. Before, those expenses had to total more than 10 percent of income.

And families of kids in private school can use tax-free 529 tuition savings accounts for children in grades kindergarten through 12, up to $10,000 per student.
